US Patent 11279609 Refrigeration systems for rapidly cooling food and drinks

Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks. Some machines include a refrigeration system to cool food or drink in a pod. Some machines include an evaporator of the refrigeration system, the evaporator including an inlet port to receive refrigerant and an outlet port to discharge refrigerant. Some machines include a processor controlling the refrigeration system. In some examples, the refrigeration system is operable to apply a freezing cycle to the food or drink in which refrigerant flows through the evaporator exchanging heat from ingredients in the pod to the refrigerant causing a temperature difference between an evaporator inlet temperature and an evaporator outlet temperature.
